SPI Receive Data
| RXDAT | Receiver Data. This contains the next piece of received data. The number of bits that are used depends on the FLen setting in TXCTL / TXDATCTL. |
| RXSSELN | Slave Select for receive. This field allows the state of the SSEL pin to be saved along with received data. The value will reflect the SSEL pin for both master and slave operation. A zero indicates that a slave select is active. The actual polarity of each slave select pin is configured by the related SPOL bit in CFG. |
| RESERVED | Reserved. |
| SOT | Start of Transfer flag. This flag will be 1 if this is the first frame after SSEL went from deasserted to asserted (i.e., any previous transfer has ended). This information can be used to identify the first piece of data in cases where the frame length is greater than 16 bit. |
| RESERVED | Reserved, the value read from a reserved bit is not defined. |
